【摘要】：数字版权保护是版权保护领域的热点问题，关系到知识产权的保护，具有重要的理论研究价值和广泛的应用背景。数字版权保护主要通过数字版权管理系统，利用加密、数字水印、数字签名等技术对数字媒体文件的上传、下载、使用等过程进行全方位的跟踪监测保护，防止数字媒体文件的不正当使用，保护版权方的合法利益不受侵犯。随着互联网的快速发展，数字媒体文件的流通变得非常容易，，对数字媒体文件的版权保护变得日益困难。数字版权保护面临的主要问题是：依赖防伪包装以及各类防伪标签进行数字版权保护的方法，对于拷贝、非法下载传播等侵权盗版已经完全失效；传统包装防伪等防侵权技术不能为公安机关打击盗版侵权提供有效溯源取证技术支持；此外，目前的数字版权管理系统在使用上普遍较为繁琐，有时为了对数字媒体文件进行严格的版权保护，往往造成一些合法用户的权益得不到保障。针对以上几个问题，我们首先对数字版权加密管理系统进行分析，采用合理的加密技术，对数字媒体文件进行加密处理，保证数字媒体文件在互联网中的安全传输，使得数字媒体文件内容得到保护；其次，为了实现打击盗版、提供有效溯源的功能，采用相应的数字水印技术，将版权、用户特征等信息嵌入到数字媒体文件中，为公安机关打击盗版侵权提供技术支持；最后，简化数字版权加密管理系统的使用流程，注重用户操作和体验，在对数字媒体文件进行版权保护的同时，有效保障合法用户的利益。在数字版权加密管理系统基本原理的基础上，利用加密和数字水印等技术，设计并实现了一种具有跟踪溯源功能的数字版权加密管理系统。经过实验测试，该系统能够有效地对数字媒体文件进行版权管理。
[Abstract]:Digital copyright protection is a hot issue in the field of copyright protection, which is related to the protection of intellectual property. It has important theoretical research value and extensive application background. Digital rights protection mainly through the digital rights management system, using encryption, digital watermarking, digital signature and other technologies to upload, download, use of digital media files to carry out omni-directional follow-up and protection. Prevent the improper use of digital media documents and protect the legitimate interests of copyright parties. With the rapid development of Internet, the circulation of digital media files becomes very easy, and the copyright protection of digital media files becomes more and more difficult. The main problems facing digital copyright protection are: relying on anti-counterfeiting packaging and various kinds of anti-counterfeiting labels for digital copyright protection, copyright infringement and piracy, such as copy, illegal download and transmission, have been completely invalidated; Traditional packaging anti-counterfeiting and other anti-infringement technology can not provide effective technical support for public security organs to crack down on piracy infringement. In addition, the current digital rights management system is generally more cumbersome, sometimes in order to strictly protect the copyright of digital media files, the rights and interests of some legitimate users are often not protected. In view of the above problems, we first analyze the digital rights encryption management system, and use reasonable encryption technology to encrypt the digital media files to ensure the secure transmission of the digital media files in the Internet. To protect the contents of digital media files; Secondly, in order to combat piracy and provide effective tracing to the source, the corresponding digital watermarking technology is used to embed copyright, user characteristics and other information into digital media files to provide technical support for public security organs to combat piracy infringement; Finally, simplify the use of digital rights encryption management system, pay attention to user operation and experience, while protecting the copyright of digital media files, effectively protect the interests of legitimate users. Based on the basic principle of digital rights encryption management system, this paper designs and implements a digital rights encryption management system with the function of tracing and tracing the source by using encryption and digital watermarking techniques. The experimental results show that the system can effectively manage the copyright of digital media files.
